In short: Great event, horrible weatherIn full: Thank you Dr Rob and the marshals for proceeding with the race in such terrible conditions. Special thanks to the gentleman from St John's Ambulance who kindly patched up my hand injury so I could finish the course, and again at the end of the race prior to heading off to A&E! Love Trionium races, and looking forward to Leith hill already!Date of review: January 1, 2014

In short: Simply PerfectIn full: My fifth attempt at the Munro. It doesn't get easier with ptactice! Great, challenging course; brilliant atmosphere and encouragement between runners; enthusiastic marshals; nice momentos and picnic at the end; and a real sense of achievement at finishing. The pain had pretty much gone after 6 days...My favourite race. Thank you Dr Rob and all the marshals. Date of review: July 8, 2013

In short: Fantastic as usual - mud, ice cold puddles, hills and glorious viewsIn full: This was my fourth attempt at the Leith Hill half, and it was muddier than ever! Very challenging course, icy temperatures (especially at the top), freezing knee-deep puddles, brilliant atmosphere with supportive runners and marshals. A perfect event if you enjoy a tough race that is perfectly organised and welcoming to all. A big thanks to Dr Rob and to the marshals who braved the weather to make the race so good.Date of review: March 26, 2013

In short: Muddy marvelousIn full: My fourth go at the KC and first in fancy dress. Excellent organisation as always, a hilly, slippery, muddy course and nice t-shirt and goodies (including soup) at the end. Thank you Dr Rob and the marshals, thoroughly enjoyableDate of review: January 11, 2013

In short: Excellent challenging trail race, lovely countryside, fantastic organisationIn full: A nicely challenging trail run in the Surrey countryside with some stunning views. Mixed terrain (the sand was tough) and some nice hills, but the whole course is runnable. The organisation and marshals were first class, and the event and atmosphere overall is very friendly. Highly recommended. Thanks to the organisers and volunteers.Date of review: September 18, 2012

In short: Wonderful run, scenic, crazily tough, brilliantly organisedIn full: Having run the Munro half on the same course several times, I should have known what to expect. But even that doesn't prepare you for the pain and fatigue that makes this run so challenging and enjoyable.The course is extremely tough, well marked (I managed to add 1.5 miles to my run by missing an obvious turning after 18 miles - I can only blame tiredness!) and has beautiful views (if you can focus on anything other than pain), organisation excellent, marshals outstanding and very encouraging, and a great atmosphere which was augmented by the arrival of the half-marathon runners part-way through the race. A real sense of achievement in completing the course, having decided this would be my last marathon I am giving serious thought to entering again for next year's "special"!Thanks to Dr Rob and the amazing marshals.Date of review: July 28, 2011

In short: Tough but very friendly race in beautiful surroundingsIn full: My third time running this race, it was as expertly organised as ever. A challenging out & back route with stunning views at half-way. All runners are very encouraging, even the winner was urging us on as he passed us on the way back from the turning point, which I thought was a great effort!. Friendly marshalls, nice t-shirt and breakfast at the end. Thanks to Dr Rob and the marshals.Date of review: March 9, 2011

In short: Brilliantly organised, nice course, very friendly and great atmosphereIn full: Thank you to TWH for organising one of the most enjoyable races I've done. The organisation was flawless, lots of marshals, traffic control, lots of people on-hand at the water stations etc. The course is undulating and the mile-long hill mid-way is tough - but the number of people out supporting along the route is amazing and helps take your mind off the pain! Receiving my medal from Kelly Holmes was also a bonus :-)This is a brilliant event. Thank you to the organisers supporters and marshals.Date of review: March 1, 2011

In short: Even tougher than last year! Fantastic race; thanks Dr Rob and the marshalsIn full: Really tough race with a "bonus hill" improvement on last year's course. Great atmosphere with some terrific fancy dress, very well organised, friendly marshals on a well-marked course, and the usual high-standard goodies at the end - soup, rolls, mug and good quality winter top. My second year at this event, it's the best way to start the new year! Date of review: January 4, 2011
